BHR62, I found a picture that is supposed to be of PVT Henry Hunter of Co G, 42nd IN. While I can't verify the picture is actually him or when the picture was taken, the soldier appears to be holding an imported Austrian model 1842 tubelock musket. The unit probably ditched these as soon as they could, but who knows when that might have been. It would take come digging in the records to find it. I hope that helps though.
